Abstract [en]

Noise is steadily on the rise in urban settings, creating a potential health hazard as well as being a nuisance. In major European cities, noise levels are so high that the majority of urban parks can no longer truly serve as recreational environments, a problem the WHO and the EU are attempting to address. This study explores various strategies that promotethe sustainable development of urban soundscapes at locations meant for rest, recreation, and social interaction. How are people affected by the combined effects of traffic and nature sounds in urban parks? To this end, we adopted a new track – the use of interdisciplinarymethodology – bringing together architectural analysis and artistic experiments, along with psychoacoustic methodology to evaluate aesthetic, emotional, perceptual, and spatial effects. A large-scale case study was conducted at a city park to explore if and how subjects are affected by purposely distributed sounds. The working hypothesis was that it is possible to cancel out traffic noise by affecting aural perceptions using a process known as informational masking. Our long-term objective is to create a scientific foundation for action plans, both pre-emptive and trouble-shooting, targeting parks and other similar public spaces that provide a relaxing environment.

Abstract [en]

The aspect of sound as a design element in an architectural context has been discussed for a long time, but there are still today very few permanent projects put into practice. The functional use of acoustics is easily comprehended when utilized to reduce unwanted noise from roads, or when it is perfected to convey speech and music in concert halls. To add sounds to create a sense of space, use it as a quality or defining identity is however still an unexplored field of knowledge. Finding the right balance between creating a quality for the space with dynamics and variety, while still being sustainable over time is challenging. The paper presents theories, methods, findings and results from a large project including nine installations. The project concerns indoor sound installations in large public spaces in Stockholm including acoustic investigations, electro acoustic installations and composition of sound installations for the specific space. The method is both scientific and art-based. The sound design is used as a way of empowering site-specific functions and architectural themes, but also in some cases as a solitary intentional characteristic quality of the space.

Abstract [en]

This article’s pivotal theme is: “How to compose a site-specific sound-art installation for a commercial space in order to improve conditions, while taking perceptual, social, aesthetical, temporal and spatial criteria into account”

The interdisciplinary, art-based research approach is derived from the concept of acousmatics, i.e. the process of apprehending any sound, the source of which is invisible. Acousmatic perception concerns the everyday identification process; when lacking visual contact with the sound source, we automatically seek references, such as social (what produces the sound and what is my relation to it?), aesthetical, spatial and temporal (e.g. orientation and demarcation). The acousmatic concept identifies phenomena based on individually, culturally and spatially conditioned experiences.

Today, a shopping culture dominates urban space. Indoor malls expose us to all types of acousmatically perceived sounds: jingles, signals, music and muzak from public loudspeakers, mobile devices, etc. In this respect, one could claim that the soundscape of the shopping culture embodies an acousmatic environment.

In 2009, the research and sound-art group Urban Sound Institute (USIT) created a permanent sound installation in a shopping mall (Gallerian) located in downtown Stockholm. This installation serves as a case study for the present paper. The artistic assignment involved the creation of a meeting place without material devices as well as the enhancement of the overall atmosphere. The research objective was to elucidate different qualities of the sound installation in regard to the acousmatics of the shopping mall, promoting discussions on the articulation of sound-space configurations in relation to time and site-specific context, issues on musical-architectural qualities as well as objective, subjective and inter-subjective interrelationships between the experience of the sound-art installation and the experience of the shopping mall soundscape. Other applied, interrelated concepts are metabolic environment and masking- and cutting effects.

Abstract [en]

The acoustic conditions in open-plan offices were investigated in a Nordic cooperation project. Measurements were carried out in five open-plan offices along with a questionnaire to gather the staff’s subjective judgments.

A programme for the acoustic measurements was drawn up, specifying how to perform the measurements and which type of parameters to measure.

The acoustic parameters included are Reverberation time T20, Early decay time (EDT), Clarity (C50), Speech transmission index (STI), Speech intelligibility index (SII), Privacy index (PI), Rate of spatial decay of sound pressure levels per distance doubling (DL2 ), Excess of sound pressure level with respect to a reference curve (DLf), and background noise levels in occupied and unoccupied offices.

A refurbishment programme was carried out in two of the offices. Measurements were performed after refurbishment and a questionnaire was completed. It is concluded that parameters relating to sound propagation, such as DL2 and DLf, are appropriate for the acoustic evaluation of open-plan spaces.

A refurbishment programme was carried out in two open-plan offices. It has been shown that DL2 and DLf are sensitive to the acoustic treatment carried out and that they also reflect an improvement in the subjective judgment as regards the acoustic environment in general. Moreover, these parameters can be converted into a (comfort) radius indicating the distance for achievement of a certain reduction of the sound level from a sound source.

This application could serve as a practical tool for the acoustic planning of open-plan offices.
